I haven't done a leak test yet as I haven't been able to get my hands on a leak down tester. Hopefully get my hands on one over the weekend.
I pulled the reeds and they look brand new. I thought that the reeds may have been on upside down. Photo attached. Not 100% sure as I didnt take a heap of notice when I pulled the reeds out as I didnt realise these were offset slightly to the left for the carb boot intake, which is also offset to the left. Would this cause it to run rich??
I did do a compression test though. I hadnt done one on this bike before so havent got anything to compare the result to but all I could get was 80psi which seems like a very low reading.

I then had a look at the piston n rings through the exhaust port. There is heaps of blow by on the piston.Could it be possible that worn rings are causing my issue. Less than 40 hours on this bike since new. Bike generally starts first kick n i thought compression felt fine..
